Why doesnt cc cleaner scan Mozilla for problems

Why doesn't cc cleaner scan Mozilla for problems I just noticed CC cleaner does not scan the web browser Mozilla or thunder bird Yet it does scan all of microsoft products

why would you leave Mozilla out Mark

Ccleaner does have routines for both these softwares. In custom clean they are on the second, apps, tab. If they don't show on your pc there, it might be that you chose a non default location for them. This can be resolved with custom loctaion command.
